 The curtain is also drawn and opened at various points in the service.The area behind the iconostasis reached through the Beautiful Gates or Angel Doors is the "sanctuary" or "altar".Within this area is the altar table, which is more often called the "holy table" or "throne"; the "apse" containing the "high place" at the center back with a throne for the bishop and the "synthronos", or seats for the priests, on either side; the "Chapel of Prothesis" on the north side where the offerings are prepared in the Proskomedia before being brought to the altar table and the holy vessels are stored; and the "Diaconicon" on the south side where the vestments are stored.
